Properties of particleboard made with Ligustrum lucidum and Pinus taeda woods
This study aimed to evaluated physical and mechanical properties of particleboard manufactured with Ligustrum lucidum wood, pure or with Pinus taeda, and to compare these panels properties with the normative requirements and those panels produced only with Pinus taeda. Panels were produced with urea-formaldehyde and tannin-formaldehyde resins, in 10% of proportion based on solid mass of dried particles. For the panels preparation, it was established nominal specific mass of 0.75 g.cm-3, specific pressure of 3.92 MPa, temperature of 160 °C and pressing time of 8 min for urea-formaldehyde resin and 10 min for tannin-formaldehyde. After the air conditioning period, samples for physical and mechanical tests were prepared. The use of only Ligustrum lucidum wood and tannin-formaldehyde, as well as the use of mixture woods and urea-formaldehyde provided panels better performance in relation to physical and mechanical properties. These panels reached mechanical properties requirements of normative codes and demonstrated the potential of L. lucidum for particleboard production.
